Specification of Letters Patent. Patented June 28, 1921.

Application filed August 11, 1920. Serial No. 402,780.

To all whom it may concern:

Be it known that I, JOHN H. PooLE, a citizen of the United States, residing at Whitman, in the county of Plymouth and State of Massachusetts, have invented new and useful Improvements in Lasts, of which the following is a specification.

This invention relates to a last containing a slot having opposed sides intersecting the heel end of the last to form an open mouth, and a serrated wheel journaled in the slot, and laterally supported by the sides of the slot, a portion of the serrated perimeter of the wheel projecting from said mouth to engage and indent the heel end of the upper 0n the last and prevent lateral displacement of said heel end, the wheel having a rolling engagement with the upper, so that it does not oppose the withdrawal of the upper from the last.

The invention is embodied in the improved means hereinafter described for connecting the wheel with the last.

Of the accompanying drawings forming a part of this specificati0n,

Figure 1 is a side view of a portion of a last embodying the invention, a part of the heel end being shown in section.

Fig. 2 is an end View of the last.

Fig. 3 is a View similar to Fig. 2, before the insertion of the serrated wheel.

Fig, 4 is a section on line 4-4 of Fig. 8.

Fig. 5 is a section on line 55 of Fig. 3.

Fig. 6 is a side view of the last attachment which includes the serrated wheel and the dowel hereinafter described.

Fig. 7 is a section on line 7-7 of Fig. 6.

The same reference characters indicate the same parts in all of the figures.

In the drawings, 12 represents a heel portion of a last, which may be of any suitable form and construction. As here shown, the portion 12 is hinged at 13 to a fore portion 14, so that the last may be shortened by swinging one of said portions relatively to the. other, as usual.

In the heel end of the last I form a slot 15, which is preferably a kerf formed by a small circular saw. Before forming the slot, I form in the heel end of the last, by means of a boring tool, a socket 16, extending lengthwise of the last, said socket interrupting the continuity of the sides of the slot 15, as indicated by Fig. 3.

The slot and socket thus formed are adapted to receive an attachment, which includes a metal dowel 17 driven tightly into the socket, and an upper-indenting member 18, which is preferably a serrated wheel, pivotally mounted in the outer end portion of said dowel, the latter being provided with a slot in its outer end portion, and the wheel being connected with the dowel by a trans verse pin. 20, on which the wheel is adapted to freely rotate.

It will be seen by reference to Figs. 1 and 2, that when the dowel is driven into the socket, the sides of the wheel 18 are laterally supported by the sides of the slot 15, so that the wheel, while adapted to freely rotate, is also adapted to prevent lateral displacement of the heel end portion of the upper on the last. When the heel end of the upper is be ing removed from the heel end of the last by the usual operation of shortening the last, the wheel rolls in contact with the upper and does not oppose the removal of the latter.

It will now be seen that the described attachment may be secured to a last by'the simple operation of driving the dowel 17 into the socket 16.

It is obvious that the dowel may be made of a material capable of being secured in the socket by glue, a suitable material being fiber such as is commonly used for dowels.

I claim:

1. In combination, a last containing a slot having opposed sides intersecting the heel end of the last, to form thereon an open mouth, and a socket interrupting the continuity of the sides of the slot and extending inwardly therefrom lengthwise of the last, and an attachment including a dowel secured in said socket, and an upper-indenting member pivotally mounted in the outer portion of said dowel, and laterally supported by the sides of the slot, said member being adapted to prevent lateral displacement of the heel end of an upper on the last, and movable in a curved path by the operation of withdrawing the upper from the heel end of the lastQso that such with than the dowel, so that the Wheel may be drawal' is not opposed by the indenting laterally supported by the sides of 2t slot 10 member. V v ormed in the last at opposite sides of said 42: A last attachment comprising a dowe1,-s0cket. adapted 'tO' be secured in a longitudinal In testimony whereof I have afiixecl my socket in the heel end of the last, anda ser- Signature.
